    About this XML formatter

    Paste XML and this tool checks it's well-formed, then reformats it with consistent, readable indentation — choose 2 spaces, 4 spaces, or tabs. Malformed XML is flagged immediately with a clear error.

    Everything runs in your browser using the native XML parser, so there's no upload and no size limit beyond what your browser can comfortably handle.
